2. Revolutionary technology that can change the world
How?

3. Outline What nanotechnology is Applications Video Pros and Cons
Conclusion

4. What is it
Nanotechnology - anything smaller than micro technology ex. Nano powders
Manipulation of matter on a very small scale “nano scale”
A sheet of paper is 100,000 nanometres thick
MNT or “molecular nanotechnology” responsible for massive changes in our environment, the way we live, and our capabilities

5. Two Main Approaches Bottom up Top down
construction of material (based on molecular recognition)
Top down
construction of nano-scale objects from larger materials (without using direct atomic control)

6. There are a number of applications of nanotechnology.
Recent Advancements
There are a number of applications of nanotechnology.

7. Water treatment Removal of industrial water pollution
Removal of salt or metals from water
Filter capable of removing virus cells from water

8. Energy production Improving the performance of batteries
More efficient, long lasting
Lighter and can be charged faster
Safer

9. Energy production
Smart Clothes - clothing that can generate electricity
Fibres having Nano generators based on piezoelectric nanofibers
Have a diameter of 500 nm.
Can change mechanical stress to electricity

10. Food Food production Food safety and health benefits Food packaging
Crop production

11. Health: Drug Delivery Ex. Bioactive glasses
Consume in the form of powder
Locates the injury
Forms new bones
